The pylon mounting assemblies include an upper pylon connection member, and a lower pylon connection box. The upper pylon connection member and the lower pylon connection box respectively define opposed lower and upper mounting surfaces which establish a mounting plane that slopes downwardly and rearwardly relative to aircraft travel direction. At least one connector assembly connects the upper pylon connection member and a lower pylon connection box to one another at the opposed respective lower and upper mounting surfaces thereof.


Landing gear doors may be opened in an emergency event, e.g., a failure of the normal landing gear actuation system that requires a gravity free-fall deployment. The retractable aircraft landing gear door actuation mechanism will include a landing gear door and a door support bracket attached to the landing gear door. The support bracket is attached to aircraft structure for pivotal movement about a pivot axis between a closed condition whereby the landing gear door covers an aircraft landing gear when retracted relative to the aircraft structure, and an opened condition whereby the landing gear door is moved laterally and upwardly relative to the aircraft landing gear when extended relative to the aircraft structure. A gear door actuation assembly is operatively connected to the door support bracket for moving the door support bracket and the gear door supported thereby between the closed and opened conditions thereof. The gear door actuation assembly will include an over-the-center spring assembly which assists in pivotal movement of the door support bracket and the gear door supported thereby from the closed condition into the opened condition thereof.

The EC Flight Path 2050 vision aims to achieve the highest levels of safety to ensure that passengers and freight as well as the air transport system and its infrastructure are protected. However, trends in safety performance over the last decade indicate that the ACARE Vision 2020 safety goal of an 80% reduction of the accident rate is not being achieved. A stronger focus on safety is required. There is a need to start a Joint Research Programme (JRP) on Aviation Safety, aiming for Coordinated Safety Research as well as Safety Research Coordination. The proposed JRP Safety, established under coordination of EREA, is built on European safety priorities, around four main themes with each theme consisting of a small set of projects. Theme 1 (New solutions for todays accidents) aims for breakthrough research with the purpose of enabling a direct, specific, significant risk reduction in the medium term. Theme 2 (Strengthening the capability to manage risk) conducts research on processes and technologies to enable the aviation system actors to achieve near-total control over the safety risk in the air transport system. Theme 3 (Building ultra-resilient systems and operators) conducts research on the improvement of Systems and the Human Operator with the specific aim to improve safety performance under unanticipated circumstances. Theme 4 (Building ultra-resilient vehicles), aims at reducing the effect of external hazards on the aerial vehicle integrity, as well as improving the safety of the cabin environment. To really connect and drive complementary Safety R&D (by EREA) to safety priorities as put forward in the EASA European Aviation Safety plan (EASp) and the EC ACARE Strategic Research and Innovation (RIA)Agenda, Safety Research Coordination activities are proposed. Focus on key priorities that impact the safety level most will significantly increase the leverage effect of the complementary safety Research and Innovation actions planned and performed by EREA.

At least a first wing spar section includes at least one upper and lower spar chord which is unitarily formed as a one-piece structure with upper and lower ends of the upright central web, respectively, while at least a second wing spar section includes at least one upper and lower spar chord which is a separate structural element integrally fixed to the upper and lower ends of the upright central web, respectively.


A system and method for damage detection and for evaluating the real operation conditions for structural platforms using structural health monitoring is integrated to a system and method that permits for the platform to provide a flexible geometric control considering a self-adapting morphing which is capable of providing better operating structural platform performance.


The present patent of invention describes a recycling process to recover fibrous reinforcing material of composite materials, particularly carbon fiber, primary reactor compound (101), for the controlled pyrolysis and oxidation of the composite material matrix (resin) at low temperature (400C to 500C) and a system for treating waste gases produced by thermal decomposition of composite material matrixes which employs a secondary reactor (201), containing within the same a thermal plasma arc (211). The main characteristic of the process, within the scope of the carbon fiber recycling, is the possibility of maintaining the fabric web, obtaining fabrics made of pure carbon fiber, without a significant amount of residues and preserving their structural characteristics. The thermal plasma allows managing high temperatures (2,000C to 15,000C) in a controlled atmosphere, which allows the dissociation of long chains of molecules into ions that are recombined to produce combustible gases and other acid or alkaline gases that are easily neutralized and retained in gas cleaning systems.


An integrated system for assessing the condition and management of a structural platform or a plurality of platforms includes a Structural Health Monitoring System (SHM), an Operational loads Monitoring System (OLM), a static, fatigue and damage tolerance analysis (FDTA) subsystem, a databank storing a maintenance plan, and a subsystem configured for damage and repair management (iSRM). The SHM may include a plurality of transducers, including a plurality of pairs of actuators and sensors; a generator device configured to excite at least one of said sensors to produce ultrasonic guided waves; and a signal processor device configured to receive the signals reflected from damage identification. The Operational loads Monitoring System (OLM) may comprise parametric models using flight parameter data. The static, fatigue and damage tolerance analysis (FDTA) subsystem may be configured to use parametric models using Finite element Models results and abacus. The databank storing a maintenance plan may comprise information relating to inspection periods and tasks of the structural platform or a plurality of platforms.
